[@jackkelly7557]

Amazing video. I'm reading a book on Python rn and the section on classes and objects is very convoluted; this simplified things greatly!!! For anyone else learning Python, I think the key is to use multiple sources when a topic is confusing.

[@rithiksaviog21ec18]

bro pls stop reading books tutorials are more powerful

[@ThomasMaltuin]

DOJO! I have only watched a bit so far but I have already noticed something special about your style of instruction. I want to say thank you for bringing out subtleties such as intentionally using different names for the formal parameters and the class variables! Using the same name is a wonderful convention, but by initially breaking that convention, students are much less likely to assume that they have to match for the code to work. This subtlety is important for a computer science student to progress from writing a little python to actually understanding what they're doing! Kudos!

[@daveprado2903]

Bro, you dont know how much of a help your videos have become, we are so thankful and hoping you the best you deserve!

[@carlmalacalza4927]

Initially did not understand that ‘self’ like ‘this’ in Java has a special meaning in Python and passes the object name. Great job.

[@yahoobolt]

To my understanding now, self means the object name being called. Because in class there can be lot of objects being created and self will default to that object.

I know this video is a few years old, but I wanted to make sure to comment and say good job! Very simple and straightforward, something a lot of these "basic python" videos lack. The way you explained attributes and the __init__ method is something that a lot of videos don't even go over or explain the why (and the reason I was watching this video in hopes it would be explained!)

Your vids are way better than the ones out of a course I paid for. Thanks so much for taking the time. Consider me subscribed!

[@TortoRacoon]

when you define the class with the function, you enter in parenthesis "(self, name, color, weight)", and when you enter the element it refers to the function like Robot("Name", "color", weight). My question is: In the function you are entering 4 things, but when defining the element you entry 3 properties. How does the code understand that "name" goes to name and not to self if self and name occupy the first position? because we saw in earlier videos that the first entry in the reference will replace the first entry in the function... what does the code understand by "self" and why is it different in this case?

[@yashdhivar9829]

Self is inbuilt by python and it gets recognised as the object that has been created so it gets ignored

Hai cs dojo what happens if we doesn't use the word self.

it still works if you use something else but i think it's just a convention. i guess it just makes it easier for someone else to read it. the one thing that needs to stay the same is the __init__ custom function

Can we make our own packages in Python and import in our program?

[@mukteshwartripathi9582]

Yes plz tell I was also having this confusion?

[@swallowedinthesea11]

Yes. Write a function etc., use the import module to use that function etc. in a file. import random # built-in module guess = int(input('Guess my number: ') x = random.randrange(101) if guess == x: print('Awesome!')

[@anuragtripathi1744]

This is awesome! After going through various linkedin courses, I needed to see your video to actually get this concept fully. Thanks!!!

Such a wonderful tutorial never gets old. It helps anyone who wants to know Python classes. Many thanks for this!

[@kiranlalasangi6096]

can explain more about __init__ function?

[@skalex055]

The init function is run when the class is first initialised. It is already there but contains no code. You can overwrite it by redefining. This means you can put all of your variables like in the video inside of it.

[@derfrueder5975]

@@skalex055 Is that comparable to an constructor?

[@daltonham2821]

How do we print more than one variable? what if we want the function introduce_self to say, for example, Hello my name is Tom I am Red I weigh 30 lbs I get an error saying I cannot concatenate

[@elfarooq7847]

I believe you can do it like this 'def introduce_self(): print ("hello my name is Tom") print ("I am Red") print ("I weigh 30 lbs")' and then call the function with 'introduce_self()'

[@dana35200]

class Robot: def ___init___ (self, name, color, weight): self.name = name self.color = color self.weight = weight def introduce_self(self): print("my name is " + self.name ) print("my color is " + self.color ) print("my weight is" + str(self.weight )) r1 = Robot("Tom", "red", 30) r2 =Robot("Jerry " , "blue", 40) r1.introduce_self() r2.introduce_self()
